Excellent job on your Jenny Curt. I ran a few articles on the FG site about adding wing ribs that way, but they were a re-pop of an earlier set of articles by another member. It really is a quick and easy way to make those card model wings look just like the real ones, same thing goes for the tail assemblies as well.
Now lets see you whip up the Navy float plane version of the Jenny. That one had a little longer wing span, a different engine and the tail was a bit different in addition to the floats. It also made this one look simple in comparison to the rigging the Navy liked to slap on them.
